Abstract

A method and a system for rendering digital content across multiple client devices are provided. Digital content is downloaded to a first client device from a network accessible library. As the digital content is rendered, a current position is tracked. A bookmark is created by setting the current position as a bookmarked position. The bookmark is transferred to a second client device, and digital content including the bookmarked position is downloaded to the second client device from the network accessible library, enabling a continuous user experience across multiple client devices.

Claims

1. A method of rendering digital content across multiple client devices comprising:

downloading first digital content corresponding to a media work from a network accessible library to a first client device via a network, the first digital content including at least a first portion of a first media stream;

storing the first digital content on the first client device;

rendering at least a portion of the first digital content on the client device;

tracking a current position in the first media stream as the first digital content is rendered;

creating a bookmark by setting the current position as a bookmarked position, the bookmark including information for identifying the media work and the bookmarked position;

transferring the bookmark to a second client device via the network;

downloading second digital content corresponding to the media work from the network accessible library to the second client device via the network, the second digital content including at least a second portion of the first media stream or at least a portion of a second media stream, the second portion of the first media stream or the portion of the second media stream including the bookmarked position;

storing the second digital content on the second client device;

rendering at least a portion of the second digital content on the second client device in dependence upon the bookmarked position;

identifying a range of content surrounding the bookmarked position in the second digital content as content to be retained;

releasing storage resources allocated to all content of the second digital content that is not identified as content to be retained on the second client device;

determining whether sufficient storage is available on the second client device to meet storage demand after releasing the storage resources allocated to the content of the second digital content that is not identified as content to be retained; and

if insufficient storage is available, narrowing the range of content surrounding the bookmarked position that is identified as content to be retained.

2. The method of claim 1, wherein the network accessible library includes one or more server devices at one or more network addresses, and wherein the one or more server devices are each capable of serving digital content.

3. The method of claim 2, wherein the first digital content is downloaded from at least one of the one or more server devices, and wherein the second digital content is downloaded from at least one of the one or more server devices.

4. The method of claim 3, further comprising managing and optimizing network connections between the first client device and the one or more server devices and between the second client device and the one or more server devices, without user interaction.

5. The method of claim 4, wherein the network connections are managed and optimized to maintain uninterrupted rendering of the first digital content and the second digital content.

6. The method of claim 2, wherein the network accessible library includes a plurality of server devices, further comprising:

collecting, by the second client device, performance metrics for each of the server devices in the network accessible library; and

selecting, by the second client device, one of the server devices in the network accessible library on the basis of the collected performance metrics, wherein the second digital content is downloaded from the selected server device.

7. The method of claim 1, wherein the first digital content and the second digital content each include audio content, illustration content, video content, audio/video content, advertising content, static graphic content, moving graphic content, or a combination thereof.

8. The method of claim 1, wherein the first media stream and the second media stream each include a plurality of digital media segments.

9. The method of claim 8, wherein the digital media segments are directly addressable.

10. The method of claim 8, wherein the digital media segments have sizes that are dependent on a network throughput rate, a media stream size, natural language gaps, a target segment size, a target segment size range, or a combination thereof.

11. The method of claim 1, wherein the bookmark is transferred from the first client device to the second client device via the network accessible library.

12. The method of claim 1, wherein the bookmark is transferred from the first client device to the second client device by bypassing the network accessible library.

13. The method of claim 1, wherein transferring the bookmark includes sending the bookmark from the first client device while the first client device is connected to the network, and receiving the bookmark by the second client device while the second client device is connected to the network;

and wherein the bookmark is transferred without requiring a simultaneous connection of the first client device and the second client device to the network.

14. The method of claim 1, further comprising:

identifying a range of content surrounding the current position in the first digital content as content to be retained;

releasing storage resources allocated to all content of the first digital content that is not identified as content to be retained on the first client device;

determining whether sufficient storage is available on the first client device to meet storage demand after releasing the storage resources allocated to the content of the first digital content that is not identified as content to be retained; and

if insufficient storage is available, narrowing the range of content surrounding the current position that is identified as content to be retained.

15. The method of claim 1, further comprising:

deleting the bookmark from the second client device; and

upon deleting the bookmark, deleting the second digital content from the second client device.

16. The method of claim 1, wherein the second digital content is rendered starting from a start position, and wherein the start position corresponds to the bookmarked position adjusted by an arbitrary value.

17. The method of claim 1, further comprising downloading third digital content corresponding to the media work from the network accessible library to the first client device via the network, the third digital content including at least a portion of a third media stream, the portion of the third media stream including the bookmarked position, the first media stream and the third media stream having different data formats;

and storing the third digital content on the first client device.

18. The method of claim 17, further comprising:

identifying a range of content surrounding the bookmarked position in the first digital content as content to be retained;

identifying a range of content surrounding the current position in the first digital content as content to be retained;

identifying a range of content surrounding the bookmarked position in the third digital content as content to be retained; and

releasing storage resources allocated to all content of the first digital content and the third digital content that is not identified as content to be retained on the first client device.

19. The method of claim 1, wherein the second digital content includes a second media stream, and wherein the first media stream and the second media stream have different data formats.

20. A system for rendering digital content across multiple client devices comprising:

a first client device;

a second client device; and

a network accessible library accessible by the first and second client devices via a network;

wherein the first client device is configured to;

download first digital content corresponding to a media work from the network accessible library via the network, the first digital content including at least a first portion of a first media stream;

store the first digital content;

render at least a portion of the first digital content;

track a current position in the first media stream as the first digital content is rendered;

create a bookmark by setting the current position as a bookmarked position, the bookmark including information for identifying the media work and the bookmarked position; and

transfer the bookmark to the second client device via the network; and

wherein the second client device is configured to;

download second digital content corresponding to the media work from the network accessible library via the network, the second digital content including at least a second portion of the first media stream or at least a portion of a second media stream, the second portion of the first media stream or the portion of the second media stream including the bookmarked position;

store the second digital content;

render at least a portion of the second digital content in dependence upon the bookmarked position;

identify a range of content surrounding the bookmarked position in the second digital content as content to be retained;

release storage resources allocated to all content of the second digital content that is not identified as content to be retained on the second client device;

determine whether sufficient storage is available on the second client device to meet storage demand after releasing the storage resources allocated to the content of the second digital content that is not identified as content to be retained; and

if insufficient storage is available, narrow the range of content surrounding the bookmarked position that is identified as content to be retained.
